The Los Angeles District Attorney won’t press charges against Buzz Aldrin for hitting a man who was aggressively trying to get him to admit that his walk on the moon was faked.

BEVERLY HILLS, Calif., Sept. 20 (UPI) — The Los Angeles County District Attorney’s office declined to file a misdemeanor battery charge Friday against former astronaut Edwin “Buzz” Aldrin, who allegedly struck a man in Beverly Hills earlier this month in a dispute over whether Aldrin’s 1969 moonwalk was a hoax.

Aldrin, 72, was confronted on Sept. 9 by Bart Sibrel, who has been challenging the authenticity of NASA’s manned moon missions, claiming that the Apollo program was a cover — designed to trick the former Soviet Union into overestimating U.S. power during the height of the Cold War.
